Another small block turbo early valiant
Well I’ve made some progress. Figured out a major cooling issue got about 60 miles on the build and now looking into a new issue. Lol. I knew I was going to be learning a lot on this project and knew that I would likely be learning some things the hard way. But didn’t think I’d run into something so quick. ♂️ After a couple test drives I had noticed that I was getting smoke/steam out my catch can. I inquired about it on a Facebook page I’m on (RWD Boosted Mopars) and the responses were overwhelming that there was a problem. So I decided to start looking into possible problems. I disconnected my catch can to see what I would find and it wasn’t what I expected.... about a half a cup of water. So I started with a compression test, all cylinders were between 130-150 a little more variant than desired I know. I pulled #6 plug out and noticed the rust color on it and suspect this is where the issue is. At this point I drained the oil (a little milky but not really bad) and drained the water. I’m going to do a leak down test, re-torque the head and do another leak down test I will keep you posted to what I find. I started off with a 6 lbs spring in the wastegate so I can ease into everything and now go crazy right off the get go. After a couple test drives and getting the cooling issue figured out I was able to go for a long enough drive to get some data. Well AGAIN looking at the data I found something I was NOT expecting! During one of the test drives I got after it a little hard and found that it produced 23.5 lbs of boost
So how in the world am I making this much boost with a 6 lbs spring in the wastegate?
